Low angle solar performance
Has my one seen data on performance by specific panel or general PV type for different incidence angles of solar radiation? All I can find so far is generic info. Jim

I wonder how different they are for panels not under glass?

If you STFW for macslab you will find that there is an enormous academic study behind that simple implementation.
IMHO, if glass reflection or thickness had any significant difference, I can't believe these folks weren't aware of that and baked it in.
I do have a program that calculates the exact angle for any date and any N Latitude at solar noon. Plus, I calculate the length of the tilt bars. I could cut the bars beforehand. I don't know enough math to do time of day. I tried tilting but it is totally incompatible with travelling. Ok for sitting still.
If you get the tilt within 15deg you will be ok. You can do that with a toy suction dart at any time of day.
Some issues just get lost in the rounding/noise.
